f22fcd4483 avformat/dashenc: Added support for Low-latency HLS(Experimental)
Apple doesn't have an official spec for LHLS. Meanwhile hls.js player folks are
trying to standardize a open LHLS spec. The draft spec is available in https://github.com/video-dev/hlsjs-rfcs/blob/lhls-spec/proposals/0001-lhls.md
This option will also try to comply with the above open spec, till Apple's spec officially supports it.
Applicable only when @var{streaming} and @var{hls_playlist} options are enabled.

c32aad1961 avformat/dashenc: Added an option to ignore io errors
When dashenc has to run for long duration(say 24x7 live stream), one can enable this option to ignore the io failure of few segment's upload due to an intermittent network issues.
When the network connection recovers dashenc will continue with the upload of the current segments, leading to the recovery of the stream.

281a21ed50 lavf/dashenc: Add support for format-specific file extensions.
The file name template options now support a new "$ext$" placeholder,
which is replaced with a filename extension specific for the selected
file format. This is useful for the new "auto" format mode, when
different streams may use different file formats, and it is not
possible to specify the correct file name extension exactly.

Resolves warnings in the log about webm segments not having webm extensions.

322e53f8ae lavf/dashenc: Add DASH segment type auto and make it the default
This commit restores the ability to create DASH streams with codecs
that require different containers that was lost after commit
2efdbf7367. It adds a new "auto" value for
the dash_segment_type option and makes it the default. When in this mode,
the segment format will be chosen based on the codec used in the stream:
webm for Vorbis, Opus, VP8 or VP9, mp4 otherwise.

1931761f18 avformat/movenc: implicitly enable negative CTS offsets for ismv
ISMV lacks any sort of edit list support, as well as tfxd is
effectively the PTS of the fragment for most intents and purposes.

Thus, if b-frames are requested without negative CTS offsets you
end up with N frames' worth of delay (tfxd PTS plus the CTS offset
of the first sample). Negative CTS offsets enable the first sample
to have CTS=DTS, and thus a/v desync due to b-frame reorder delay
is avoided.

5717cd80dc avformat/movenc: creating producer reference time (PRFT) box
The producer reference time box supplies relative wall-clock times
at which movie fragments, or files containing movie fragments
(such as segments) were produced.
The box is mainly useful in live streaming use cases. A media player
can parse the box and utilize the time fields to measure and improve
the latency during real time playout.

2efdbf7367 avformat/dashenc: Added option for Segment file format
Right now segment file format is chosen to be either mp4 or webm based on the codec format.
This patch makes that choice configurable by the user, instead of being decided by the muxer.

Also with this change per-stream choice segment file format(based on codec type) is not possible.
All the output audio and video streams should be in the same file format.

d10cefbfe5 avformat/dashenc: addition of segment index correction logic
The logic is applicable only when use_template is enabled and use_timeline
is disabled. The logic monitors the flow of segment indexes. If a streams's
segment index value is not at the expected real time position, then
the logic corrects that index value.

Typically this logic is needed in live streaming use cases. The network
bandwidth fluctuations are common during long run streaming. Each
fluctuation can cause the segment indexes fall behind the expected real
time position. Without this logic, players will not be able to consume
the content, even after encoder's network condition comes back to
normal state.

ab789e184c avformat/dashenc: segmentation at the configured segment duration rate
When use_template is enabled and use_timeline is disabled, typically
it is required to generate the segments at the configured segment duration
rate on an average. This commit is particularly needed to handle the
segmentation when video frame rates are fractional like 29.97 or 59.94 fps.

01ba52852d avformat/dashenc: replacing 'min_seg_duration' with 'seg_duration'
There are use cases where average segment duration needs to be configured
and muxer is expected to maintain the average segment duration. So, using
the name 'min_seg_duration' will be misleading. So, changing the parameter
name to 'seg_duration', where it can be minimum segment duration or average
segment duration based on the use-case. The additional updates needed for
this functinality are made the sub-sequent patches of this patch series.

07e4be7ec9 movenc: Add an option for enabling negative CTS offsets
This reduces the need for an edit list; streams that start with
e.g. dts=-1, pts=0 can be encoded as dts=0, pts=0 (which is valid
in mov/mp4) by shifting the dts values of all packets forward.
This avoids the need for edit lists for such streams (while they
still are needed for audio streams with encoder delay).

This eases conformance with the DASH-IF interoperability guidelines.
